- Hold the devices with the back covers to each other (NFC antennas are usually located there).
- Wait for the beep - the transmission will start automatically.
Limitations:
- π± It only works between Android 4.0 devices+.
- π You can only transfer small files (up to 1-2 MB). For large volumes, use Mi Share or Bluetooth.
- π Both phones should be unlocked.
β οΈ Attention: MIUI 13+ Android Beam can be called a fast transfer or NFC-If you don't find it, update the firmware.
Why is Android Beam slower than Bluetooth?
Using NFC for Smart Devices
Redmi Note 8 Pro can be used as a universal control panel for smart devices: tags, locks, lamps, etc. For example, using the NFC-marker (NFC_tags) You can:
- π Open doors: Set up a tag to unlock the smart lock (supported by Xiaomi Smart Lock, Nuki, etc.).
